Washi Z Near Infra Red 400 - 35mm 24Exp

Washi Z 35mm Near Infrared Black & White Film (24 Exposures)

Washi Z is a specialist 35mm black and white negative film with extended sensitivity into the near infrared spectrum. Originally produced for aerial vegetation mapping, it offers strong contrast and excellent separation between different shades of green, making it a distinctive choice for landscape photography. Rated at ISO 400 and supplied in a recycled 35mm cassette with 24 exposures, it rewards careful handling and considered processing.

Why We Like It

This is a film for photographers who enjoy experimenting and slowing the process down. Washi Z really comes into its own outdoors, where foliage, grass and trees gain a luminous, almost glowing separation, even under flat or cloudy skies. Pairing it with a red filter can exaggerate the infrared effect further, darkening skies and lifting greens and reds. It is not a casual snapshot film, but for thoughtful landscape work or creative projects, it can produce results that feel genuinely different from standard black and white stocks.

Processing notes: Washi Z must be handled and processed in total darkness, as it is not safe under a standard darkroom safelight. It can be developed using conventional black and white developers at ISO 400. Reliable starting points include Ilfosol 3 (1+9, 4.5 minutes at 20°C), Rodinal (1+25, 7 minutes at 20°C), D-76 stock (10 minutes at 20°C) or XTOL stock (8 minutes at 20°C). If using an unlisted developer, times for Ilford Delta 400 are a sensible reference. When loading, avoid bright light to prevent light piping, and advance a few blank frames before shooting.
